Trail Maintenance at Muttontown Preserve

Nassau County is home to countless preserves that serve as habitat and refuge for the native plants and wildlife that represent Long Island’s unique ecology.  These preserves act as gateways for local communities by allowing access to untouched natural environments, and many organizations utilize preserves to host educational trail walks and promote environmental values and stewardship. 


The Nassau County Soil & Water Conservation District has been working to establish a system of trails in this ecologically unique county preserve. 

Native and Invasive Species Education

Nassau County SWCD planted a Bat Box in Pond Park, Great Neck Estates as a part of our Native and Invasive and Native Species Education and Outreach Program.


Once established this will provide a vital habitat for our Long Island native Little Brown Bats (Myotis lucifugus). Native bat species help control populations of mosquito, beetles and other pests, a single little brown bat can catch 600 mosquitoes in just one hour! Bats also play essential roles in native plant pollination and the dispersal of seeds. 

A Day in the Life

A Day in the Life is a program organized by the South Shore Estuary Reserve focused on environmental education, community engagement and water-quality monitoring.  students will get the opportunity to collect water quality samples, learn about ecosystem services and engage with local flora & fauna.


After the field trip event, the data collected by student groups is processed and shared for analysis—an activity in which students are encouraged to participate in.  This can range from tracking water & soil health throughout Nassau County to GIS analysis of the collected data.

Permeable Pavement 

The Nassau County Soil & Water Conservation district helped install Permeable Pavement at the Bayville Community Center. 


This project was made possible due to a grant from the National Fish and Wildlife Foundation. Permeable pavement allows for the infiltration of storm water and helps protect an area from flood damage.

Rain Garden Revitilization

Rain Gardens are essential in recharging underground aquefors, of which many Long Island residents use for water. A Rain Garden is designed to capture stormwater runoff and filter it as it enters the ground. It is imperative to clean this "first flush" as it carries the greatest amount of pollutants. 


Raingardens are designed to improve the quality of the stormwater before it enters the groundwater or surface waters. A raingarden can be designed and constructed in various ways to best suit the need of the surrounding area, local aesthetics, or for educational purposes.

The Conservation District has designed and installed numerous raingardens across Nassau County through a number of partnerships and grant programs with plans to continue maintaining
